If iSCSI targets are present in the computer, there is high probability that the issue will occur.</li></ul><p class="ng-scope" role="document"><strong class="sbody-strong">Resolution</strong><br/><br/>If the event logs indicate that many reconnections are occurring, work with your iSCSI and network fabric vendor to help diagnose and correct the reason for the failure to maintain connections to iSCSI targets. Make sure that iSCSI targets can be accessed over the current network fabric. Install updated fixes when they become available. This article will be updated with the specific KB article number of the fix to install when it becomes available.<br/><br/><strong>Note:</strong> We do not recommend that you uninstall any of the March, April, May, or June security rollups. Doing so will expose the computers to known security exploits and other bugs that are mitigated by monthly updates. We recommend that you first work with iSCSI target and network vendors to resolve the connectivity issues that are triggering target reconnects.</p></div></div></div><p> </p><h2>How to get this update</h2><div><p><span>To get the standalone package for this update, go to the <a href="http://catalog.update.microsoft.com/v7/site/Search.aspx?q=KB4025333"><span><u>Microsoft Update Catalog</u></span></a> website.</span></p><p><strong>File information</strong></p><p>For a list of the files that are provided in this update, download the <a data-content-id="" data-content-type="" href="http://download.microsoft.com/download/E/D/1/ED190AD4-C200-413B-8D24-74AD23BC30AF/4025333.csv" target="">file information for update 4025333</a>. </p></div><h2>Prerequisites</h2>You must have the following update installed: <div class="indent"> <a href="https://support.microsoft.com/help/2919355"> 2919355</a> Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 update: April 2014</div></body></html>
